Using an international sample of firms from 22 developed countries, we find that a portfolio strategy based on firms' foreign sales information yields future returns of more than 10% p.a. globally. The return spread due to foreign information is substantial across different geographical regions and cannot be explained by traditional risk factors, firm characteristics, and industry momentum. Our results are in line with limited attention of investors being the main driver of this effect worldwide.enForeign informationreturn predictabilitylimited attentionjournal article
